I've typically only used the single hole plate if I have it available. Too many pointy triangle ends have gotten squished into the zigzag plate.
My current Bernina is smarter than me and tells me no way if I try to adjust the stitch width.
My poor portable Brother on the other hand where the default stitch is not in the middle, well -- many of us know exactly the noise of it hitting the foot and my foot has this little divot in it now.
